Why embankments and cuttings are common knotweed sites, and what owners of neighbouring gardens should do.
Railway cuttings, the M61 embankments and the old works sidings around Horwich and Westhoughton are cut back only now and then. That makes them quiet places for a stand to grow, and fragments can be carried along them or moved by maintenance work.
Check the back boundary every spring and again in midsummer. A dated photograph of any canes beyond the fence is useful evidence.
Rail and highway land is owned by organisations with their own reporting routes. A survey of your side gives you something concrete to send them, with the position of the stand and the date you found it.
